Temperature

The air temperature in the

battery string environment

is above or below

configured thresholds.

Default:

50.0° F (10° C): low

threshold

95.0° F (35° C): high

threshold.

Problem:

• Uncorrected high temperature can cause

permanent damage to the batteries.

• Uncorrected low temperature can cause a

reduction in battery runtime.

Response: Check temperature control and

ventilation systems in the room, and check

for overheated batteries (usually caused by

overcharging).

Input Contacts Activation of input

contacts triggers an

alarm.

Check the status of the external monitoring

device that sent the input signal.
